Abstract

A composition inhibits respiratory viruses and a method prevents and treats a respiratory. Respiratory viral infections are extremely common clinically, but the current therapeutic drugs for viral infections still cannot meet the treatment needs. An inhalant inhibits respiratory viruses and adopts a method of inhaling high-temperature acetic acid steam for prevention and treatment. Acetic acid in the high-temperature steam can release hydrogen ions to inactivate viruses in the respiratory tract, so as to prevent the onset of the disease and provide a therapeutic effect. In addition, the composition can be used to inhibit fungi and bacteria in vitro and prevent skin diseases and respiratory diseases caused by bacteria and fungi. The prevention and treatment method is easy to implement and has low costs and important clinical application value.

Description

BACKGROUND

Technical Field

The present invention belongs to the technical field of biomedicine, and specifically relates to a composition for inhibiting respiratory viruses and a respiratory virus prevention and treatment method.

Related Art

Disclosure of the related art information is only intended to increase the understanding of the overall background of the present invention, and is not necessarily regarded as an acknowledgement or in any form suggesting that the information constitutes the prior art known to those of ordinary skill in the art.
As one of the common clinical diseases, respiratory viral infectious disease has complex etiology and high viral variability, which is prone to outbreaks in the population. At present, there are as many as 100-200 kinds of viruses that can cause respiratory infections, which can be divided into RNA viruses and DNA viruses. The most common pathogenic viruses include influenza viruses, parainfluenza viruses, respiratory syncytial viruses, adenoviruses, rhinoviruses and coronaviruses. In recent years, there have been several new highly pathogenic viruses which mainly infect the respiratory tract, such as SARS coronavirus (SARS-CoV), H5N1 human avian influenza A virus and 2009 novel H1N1 influenza A virus. Due to the aging society, organ transplantation, the application of immunosuppressants in immunity-related diseases, the increase in the incidence of human acquired immunodeficiency syndromes, the increasing number of patients and other factors, the incidence of new or recurring respiratory viral infections is increasing, and the fatality rate of some viral infections is extremely high. Therefore, this type of diseases has become a public health problem which cannot be ignored.
Novel coronavirus pneumonia (Corona Virus Disease 2019, COVID-19) refers to the pneumonia caused by the 2019 novel coronavirus infection. The structure of the novel coronavirus includes a protein coat and a single-stranded RNA carrying genetic materials. This simple structure reduces the difficulty of replication of the novel coronavirus and increases the spread of the virus. The single strand makes the novel coronavirus more likely to mutate, thereby increasing the difficulty of drug treatment. The main transmission routes of the novel coronavirus include respiratory droplet transmission, contact transmission, aerosol and fecal-oral transmission. Epidemiological investigations show that people of all ages may be infected, and most victims are adults, among whom the elderly, the weak and the sick seem to be more likely to be infected.
Respiratory viral infections are clinically very common, but there are few corresponding therapeutic drugs. Commonly used clinical antiviral drugs mainly include oseltamivir, amantadines, ribavirin, ganciclovir and Chinese patent medicines containing Scutellaria baicalensis or andrographolide, and the main prevention methods for respiratory viral infections are vaccine prevention, personal hygiene, disinfection of the external environment and the like. The current treatment and prevention drugs cannot fully meet the current needs for the treatment of respiratory viral infections, and the speed of research and development of related drugs is far lower than the speed of virus transmission and mutation. Currently commonly used disinfection methods include the use of alcohol, 84 disinfectant, etc., but disinfecting the external environment of the human body such as the surrounding air, hands and feet cannot kill viruses that have already entered the human respiratory system, and the only thing the infected people can do is to wait for the viruses to replicate and cause diseases.

SUMMARY

In view of the research background above, an objective of the present invention is to provide a method for preventing and treating respiratory virus-related diseases by inactivating respiratory viruses. In order to achieve this objective, the present invention provides the following technical schemes:
According to a first aspect of the present invention, a composition for inhibiting respiratory viruses is provided, where acetic acid is used as an active ingredient in the composition.
The research of the present invention proves that hydrogen ions can inactivate viruses adhering to the human respiratory tract, and acetic acid, as a weak acid, can provide hydrogen ions in a dose of inactivating respiratory viruses at a tolerable concentration, thereby inactivating viruses in the human respiratory tract and preventing and treating respiratory viral infectious diseases.
In addition, the composition includes other auxiliary therapeutic ingredients, such as ethanol, oxygen and anti-allergy ingredients. Ethanol can help inactivate viruses and bacteria and can also help relieve the sensory stimulation of the patient caused by acetic acid. In addition, when acetic acid is used for treatment, medical oxygen is mixed to increase the blood oxygen concentration of the patient to strengthen the cardiopulmonary function of the patient, thereby improving the effect of inactivating respiratory viruses.
According to a second aspect of the present invention, an inhalant for inhibiting respiratory viruses is provided, where the inhalant includes the composition according to the first aspect.
The inhalant of the present invention also includes a composition scheme containing anti-allergy ingredients. Due to individual differences, different people have different tolerances to the ingredients of the above composition. In order to eliminate the possibility of drug allergy and ensure the safety of medication, the inhalant also includes anti-allergy ingredients.
According to a third aspect of the present invention, a respiratory virus prevention and treatment method is provided, where the prevention and treatment method includes inhalation of the inhalant for inhibiting respiratory viruses according to the second aspect.
It is believed through the research of the present invention that in the acetic acid steam at high temperature, acetic acid molecules can ionize to produce more hydrogen ions, and hydrogen ions are the main virus inactivating substances. As the temperature of the steam increases, the ionization output is also increased, and the kinetic energy is also increased substantially. Therefore, increasing the inhalation temperature of the steam as much as possible can further improve the effect of inactivating viruses in the respiratory tract.
According to a fourth aspect of the present invention, a novel coronavirus pneumonia prevention and treatment method is provided, where the method includes the steps of the respiratory virus prevention and treatment method according to the third aspect.
In addition, the novel coronavirus pneumonia treatment method provided by the present invention includes the use of the inhalant in combination with anti-novel coronavirus pneumonia drugs, where α-interferon and the like can be mixed with the inhalant and administrated in an inhalation way; or oral administration or intravenous injection of other anti-novel coronavirus pneumonia drugs is carried out while the inhalant is used for treatment.
According to a fifth aspect of the present invention, application of the composition according to the first aspect in inhibiting fungi and/or bacteria in vitro is provided.
The composition provided by the present invention can also be applied in inhibiting fungi and bacteria in vitro and in the respiratory tract to prevent fungi or bacteria from adhering to the surface of the skin or respiratory tract to cause diseases. The method for preventing respiratory fungi and bacteria is the same as that of the third aspect. The method for inhibiting fungi and bacteria on the skin surface includes the use of the high-temperature steam described in the second aspect to fumigate the skin surface.
The beneficial effects of one or more of the above technical schemes are:
The composition and inhalant provided by the present invention also have a good effect of killing viruses entering the respiratory system, and can be used for prevention and treatment as well as environmental disinfection. It is proved through experiments that those who use this method for disinfection for about 3 minutes once per day will not be infected with the novel coronavirus; and those who have been infected with the novel coronavirus will recover within 4 days by using this method at the early stage.
In addition, the inhalant mentioned in the present invention has extremely low costs. According to the current price level, each person can be protected from infection with only RMB 0.1 yuan per day, and each patient can be cured with less than RMB 10 yuan.
The inhalation disinfection method mentioned in the present invention does not have any toxic or side effects on the human body. After killing the viruses, the high-temperature hydrogen ions in the human body can be reduced to normal body temperature in about 0.1 second, form weakly acidic acetic acid with acetate ions, and be excreted with the sputum.
